Distribution

Africa. Southwest Mauritania, Senegal, Gambia, Guinea-Bissau, southern Mali, Burkina Faso and Ghana east to southern Chad, northern Central African Republic, southern and eastern Sudan, South Sudan, northeast Democratic Republic of the Congo, central and southern Ethiopia, northwest and southern Somalia, northwest Uganda and north-central Kenya south to central Tanzania.

Formerly lumped with Southern Masked Weaver (P. velatus), Katanga Masked Weaver (P. katangae), Lufira Masked Weaver (P. ruweti) and Tanzanian Masked Weaver (P. reichardi).

Subspecies

Two subspecies usually recognized[1].

Differences are variable and some authors consider the species to be monotypic [2].

Habitat

Dry savanna woodland and arid scrubland.

Behaviour

Diet

Includes seeds and insects, also nectar from Leonotis nepetifolia; birds will bite flowers off at base to steal nectar.

Breeding

They are polygynous nesting in small colonies in trees. The male builds an onion shaped nest from woven green grass. Clutch of 2-4 variable blue-white, pink-white or greenish, white eggs sometimes with fine black spotting, others with red or violet flecks.

Vocalisation

Song is a dry sputtering squeaky trill, interspersed with rasps, whistles and chirps.

Movements

Nomadic flocks form in non-breeding season. Movements likely, influenced by food supply.
